测试了1天半的shell

testsrv@node150:~$ ps -ef | grep fa
testsrv   1327     1 11 21:49 ?        00:00:17 java -jar faceFeature-demo-0.0.1-SNAPSHOT.jar
testsrv   1530  1493  0 21:51 pts/0    00:00:00 grep --color=auto fa
testsrv@node150:~$ cat /etc/rc.local 
#!/bin/sh -e
# rc.local

# This script is executed at the end of each multiuser runlevel.

exec 2> /tmp/rc.local.log  # send stderr from rc.local to a log file
exec 1>&2                      # send stdout to the same log file
set -x                         # tell sh to display commands before execution


su testsrv

echo `whoami`

#export MYHOME=/home/testsrv
#export PATH=/home/testsrv/bin:/home/testsrv/.local/bin:/opt/java/jdk1.8.0_231/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin


#/bin/sleep 60 && /home/testsrv/face.sh &

export JAVA_HOME=/opt/java/jdk1.8.0_231
export CLASSPATH=.:${JAVA_HOME}/lib: 
export PATH=${JAVA_HOME}/bin:$PATH

#cd /opt/face
su testsrv -c "export JAVA_HOME=/opt/java/jdk1.8.0_231; export CLASSPATH=.:${JAVA_HOME}/lib:; export PATH=${JAVA_HOME}/bin:$PATH;cd /opt/face;java -jar faceFeature-demo-0.0.1-SNAPSHOT.jar > face.log &"


exit 0

注意： 千万不要以root用户去操作普通用户home下的资源；shell一定会报错；例如：

su testsrv -c "export JAVA_HOME=/opt/java/jdk1.8.0_231; export CLASSPATH=.:${JAVA_HOME}/lib:; export PATH=${JAVA_HOME}/bin:$PATH;cd /opt/face;java -jar faceFeature-demo-0.0.1-SNAPSHOT.jar > face.log &"


改为

su testsrv -c "export JAVA_HOME=/opt/java/jdk1.8.0_231; export CLASSPATH=.:${JAVA_HOME}/lib:; export PATH=${JAVA_HOME}/bin:$PATH;cd /home/testsrv/;java -jar faceFeature-demo-0.0.1-SNAPSHOT.jar > face.log &"

一定会错误；

即使chmod 777 testsrv 了也没有用； 大部分错误都是权限问题

cd /opt/face;  不能改为 cd /home/testsrv/ ；会报权限问题

nginx 开机自启动

Ubuntu16.04


sudo apt-get install nginx  # 安装


sudo apt-get purge nginx nginx-common # 卸载所有东东，包括删除配置文件。


安装之后自动开机启动的；


如果该坏了； 备份配置文件；卸载重新安装；一定有用；
